Oklahoma Secretary of State - Apostilles

The Secretary of State is the office in Oklahoma authorized to issue an Apostille or Authentication for documents going to a foreign country. Apostilles are accepted by countries that are a party to the Hague Conference on Private International Law. A listing of the countries which are a party to the Conference is available at www.hcch.net. Countries that are NOT a party to the Hague Conference, will be issued an Authentication.

An Apostille or Authentication may be attached to an original notarized document, or a certified copy of a recordable document issued by an Oklahoma statewide officer. Documents may include the following: Oklahoma birth certificate, marriage license, divorce decree, background check, Power of Attorney, survivor certificate, school transcript, and adoption document. Please note ** Any marriage license, divorce decree, and any court certified document, must be dated within the past year. To obtain a current certified copy of a court issued document, please contact the County Court Clerk's office in which the document was issued. To obtain a certified copy of an Oklahoma birth certificate, please contact the Oklahoma State Department of Health. (405) 426-8880.

The statutory fee for an Authentication is $20.00 per notarial act, certified document, or international adoption proceedings.
